I know that the Brazilian official who ordered the flight and the photos did it to prove that this group exist, in order to argue for preservation of land around them, but this might be the saddest picture I have ever seen.
As a connoisseur of the Doom, I ogle a lot of tragic stuff. This is, I think, the heartbreaker of all time.
Humans are such fragile things. No shiny exoskeleton, no big teeth or claws, just our strange, wondrous sense of community to protect us- and in most of our worlds, isn't that sense of community kind of dying (like, well, our oceans, etc?) I mean, Bowling Alone blah blah blah. Oh heck.
I hope with all of my heart that they are left in peace.
